All those savings anticipated from the sweeping tax reform bill signed into law Friday morning by President Donald Trump shift the spotlight away from Washington and to American businesses already flush with cash and corporate profits.

As a corporate town, Dallas is a good place to examine how permanent tax cuts for corporations and temporary ones for individuals will flow through the economy. The changes, which go into effect in January, represent the most significant overhaul of America's tax system since the 1980s.

But how will companies share their windfalls? Some worry that corporations will pull out the same playbook they've used in recent years that has helped fuel the stock market: Spend billions buying back their own shares and make dividend payouts to shareholders.

Regular folks are looking at that spontaneous bonus from AT&T and wondering if that's happening at their places of work. But major employers already have bonus plans in place. Both Southwest and American airlines, for example, have employee profit-sharing plans, and so those workers could see a direct impact from some of the tax cuts.

Randall Stephenson, CEO of Dallas-based AT&T, took the lead Wednesday with the attention-grabbing gesture to give $1,000 bonuses to more than 200,000 employees.

Texas Capital Bank CEO Keith Cargill said Friday that the bank is also planning $1,000 bonuses for over 900 employees who aren't already eligible for bonus compensation. And next year, the bank will be looking for more ways "to invest in employees as a result of the tax bill."

By February, rank-and-file employees may see more money in their paychecks, as the IRS sends employers new payroll tables. Some employers will be paying higher wages to hourly workers. Separate from tax reform, 18 states — but not Texas — have minimum wage increases coming as the calendar shifts to 2018.

Accountants will be working overtime to assess the impact on individual companies and industries they audit.

Southwest CEO Gary Kelly has said that U.S. airlines are some of the most heavily taxed companies, so the industry is seeing the cuts as a way to be more competitive on a global stage.

Retailers are pumped. Besides lifting the economy, which benefits consumer spending overall, the landmark legislation makes retailers "winners," said Matthew Shay, CEO of the National Retail Federation. Retail, like airlines, is another industry that complained it hasn't had the tax breaks that other industries such as real estate and energy have enjoyed under existing tax laws.

The retail sector "receives few of the tax breaks that benefit other sectors of the economy and pay the highest effective tax rate of any industry," Shay said.

Toyota spokesman Scott Vazin wrote in emails Thursday that it was too early for the Japanese auto giant to "fully assess" the implications of the tax revamp on its U.S. operations, which the company moved from Southern California to Plano this year.

However, he said, "Toyota will continue to increase its investment in the U.S., which began 60 years ago." In the new year, that will include building its planned $1.6 billion joint assembly plant with Mazda. That, he wrote, is expected to employ 4,000 people. Toyota announced a new alliance with Mazda in August, sparking a courting spree by states hoping to land the factory.

Vazin added that it was unlikely the automaker would follow AT&T's lead. Toyota's bonus structure is "set many months in advance," he said, to reward both the performance of individual workers and the company.

"We take external and internal factors into consideration when determining our bonus payout," he said.
